Bold values are the worst case: easiest to exploit or largest impact.

Attack Vector: Network: The vulnerable component is bound to the network stack and the set of possible attackers extends beyond the other options listed, up to and including the entire Internet. Such a vulnerability is often termed 'remotely exploitable' and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers).
Attack Complexity: Low: Specialized access conditions or extenuating circumstances do not exist. An attacker can expect repeatable success against the vulnerable component.
Privileges Required: Low: The attacker is authorized with (i.e., requires) privileges that provide basic user capabilities that could normally affect only settings and files owned by a user. Alternatively, an attacker with Low privileges may have the ability to cause an impact only to non-sensitive resources.
User Interaction: None: The vulnerable system can be exploited without any interaction from any user.
Scope: Unchanged: An exploited vulnerability can only affect resources managed by the same security authority. In this case, the vulnerable component and the impacted component are either the same, or both are managed by the same security authority.
Confidentiality: None: There is no loss of confidentiality within the impacted component.
Integrity: High: There is a total loss of integrity, or a complete loss of protection. For example, the attacker is able to modify any/all files protected by the impacted component. Alternatively, only some files can be modified, but malicious modification would present a direct, serious consequence to the impacted component.
Availability: High: There is total loss of availability, resulting in the attacker being able to fully deny access to resources in the impacted component; this loss is either sustained (while the attacker continues to deliver the attack) or persistent (the condition persists even after the attack has completed). Alternatively, the attacker has the ability to deny some availability, but the loss of availability presents a direct, serious consequence to the impacted component (e.g., the attacker cannot disrupt existing connections, but can prevent new connections; the attacker can repeatedly exploit a vulnerability that, in each instance of a successful attack, leaks a only small amount of memory, but after repeated exploitation causes a service to become completely unavailable).

Exploitation evidence

Disclosed: evidence found.
CVE published 19 Feb 2026
Detectable: no evidence on record.
No public nuclei template indexed
Weaponised: no evidence on record.
No public exploit code indexed in Metasploit or Exploit-DB
Exploited in the wildExploited: no evidence on record.
Not in CISA KEV and no source reports exploitation

No attack traffic recorded by OffSeq Mirage sensors

A missing step is not evidence of safety. Sources: cve.org (opens in a new tab), the Metasploit, Exploit-DB and nuclei-templates index as of 2026-10-26.

Disclosed: The CVE record is public on cve.org. Its publication is t = 0.
Detectable: A public nuclei template can find exposed instances, for defenders and attackers alike.
Weaponised: Public exploit code exists in Metasploit or Exploit-DB, or CISA SSVC reports a public proof of concept.
Exploited in the wild: CISA KEV lists it, CISA SSVC rates exploitation active, or a source reports attacks.
Observed by OffSeq Mirage: OffSeq Mirage honeypot sensors recorded attack traffic for this CVE, or found exposed hosts without attack traffic.

Moments are spaced evenly, not to scale; a dashed line marks a gap of six months or more. Deltas count from t = 0. Sources that give only a date (CISA KEV, Exploit-DB, or a time of exactly 00:00Z) read “same day” rather than hours. Metasploit modules carry the flaw’s disclosure date, not their release date, and nuclei templates carry no date, so both appear above but not on the timeline.

What to do

Upgrade Unisphere for PowerMax and PowerMax to 10.3.0.1 or later.

AI-suggested

1. Monitor Dell’s official channels closely for the release of security patches addressing CVE-2026-26362 and apply them immediately upon availability. 2. Restrict network access to the Dell Unisphere for PowerMax management interfaces using firewalls and network segmentation to limit exposure to trusted administrators only. 3. Implement strict input validation and sanitization controls on any interfaces exposed to users or automated systems to prevent path traversal attempts. 4. Employ intrusion detection and prevention systems (IDS/IPS) with signatures or heuristics capable of detecting path traversal attack patterns targeting storage management systems. 5. Conduct regular audits and integrity checks on critical system files to detect unauthorized modifications promptly. 6. Enforce the principle of least privilege for all user accounts interacting with the management system to minimize potential attack vectors. 7. Maintain comprehensive logging and monitoring of all access and configuration changes to enable rapid incident response. 8. Consider deploying application-layer gateways or proxies that can filter and validate requests to the management interface.

Description

Dell Unisphere for PowerMax, version(s) 10.2, contain(s) a Relative Path Traversal vulnerability. A low privileged attacker with remote access could potentially exploit this vulnerability, leading to unauthorized modification of critical system files.

Impact

For European organizations, the exploitation of this vulnerability could lead to unauthorized modification of critical system files within Dell PowerMax storage management environments. This can result in data corruption, disruption of storage services, and potential downtime affecting business continuity. Sectors such as finance, healthcare, telecommunications, and government, which rely heavily on robust and secure storage infrastructure, could experience operational disruptions and data integrity issues. The high integrity and availability impact means attackers could alter system configurations or disrupt storage operations, potentially leading to data loss or service outages. Given the remote exploitability and low privilege requirement, attackers could leverage this vulnerability as a foothold for further lateral movement or to disrupt critical infrastructure. The absence of known exploits currently provides a window for proactive defense, but the risk remains significant due to the critical nature of the affected systems.

CWE-23Relative Path Traversal (opens in a new tab)
Base weaknessOWASP Top 10 A01:2025: Broken Access Control (opens in a new tab)
The product uses external input to construct a pathname that should be within a restricted directory, but it does not properly neutralize sequences such as ".." that can resolve to a location that is outside of that directory.
Implementation · Input Validation
Assume all input is malicious. Use an "accept known good" input validation strategy, i.e., use a list of acceptable inputs that strictly conform to specifications. Reject any input that does not strictly conform to specifications, or transform it into something that does.
Implementation · Input Validation
Inputs should be decoded and canonicalized to the application's current internal representation before being validated (CWE-180). Make sure that the application does not decode the same input twice (CWE-174).
Operation · Firewall
Use an application firewall that can detect attacks against this weakness. It can be beneficial in cases in which the code cannot be fixed (because it is controlled by a third party), as an emergency prevention measure while more comprehensive software assurance measures are applied, or to provide defense in depth.
